b. Installation. Install wiring harnesses in accordance with the following steps, as applicable.
(1) Form harness to approximate its final configuration in the air conditioner.
(a) Solder connections that do
not have provision for other terminal connections.
(b) Attach lug-type terminals to binding screws, and tighten screws.
(c) Push on spade-type terminals.
(d) Connect plugs to
receptacles, and screw on
retaining sleeve.
(e) Install receptacles in
openings, and secure with four screws through corners, and self-locking nubs if
re-
quired.
(3) Install loop clamps as required, and secure with screws and nuts.
(4) Install rubber grommets as follows:
(a) Form split grommet around wiring harness on one side of hole.
(b) Insert a loop of tough string or flexible wire all around the circumferential groove of the grommet, and
pass ends of string through hole.
(c) Press grommet against hole on one side, and pull string completely through from other side. This will
seat the grommet in the hole.
4-50. Repair.
Repair defective wiring harnesses by replacing faulty parts, as appropriate, in accordance with the following steps:
(1) Measure a length of new wire of equivalent gauge and length to the wire being replaced.
(2) Remove 1/4-5/16 inch (6-8 mm) of insulation from both ends of wire.
(3) If connecting to a plug or receptacle without an insulation grommet, slip a one-inch length of heat-shrink tub-
ing over insulation. Solder connection to pin or socket, and slide heat-shrink tubing over soldered connection. Heat tub-
ing with a match or use other suitable means to shrink it in place.
(4) If connecting to a terminal lug, slip lug onto bare end of wire until wire bottoms in lug. Crimp lug to secure.
(5) Form replaced wire along outside of wiring harness, and lace or tie at 3-inch intervals.
(6) If replacing a defective plug or receptacle, cut away heatshrink tubing being careful to avoid cutting into in-
sulation of the wire. Unsolder each connection, one at a time, and install a new one-inch length of heat-shrink tubing
over wire. Insert wire into the same pin or socket on the new connector as it came from on the old connector. Solder the
connection, slip tubing over the connection, and heat tubing to shrink it onto connection. Repeat for each wire until com-
plete.
